Thanks, Dimitre.  I got the insert_breaks template to work with your
suggested snippet shown above to create nodes instead of just a text
string.  Indeed this was one of my early attempts.  The problem remains
that there is more than one substitution required, thus the reason for
variable, "t1".  I pass "t1" to the next substitution -- a simple string
substitution, no node creation -- and subsequently lose the <br />
element. 

After bustin' my head against the wall for another few hours with
various combinations of node-set() calls here and there, I decided to
take a look at EXSLT to see what the string library had implemented, and
Jeni did not let me down -- a full-blown replace any darn thing(s) with
any darn thing(s) 'til your heart's content.  Final version and an
example of using str:replace for multiple substitutions with both string
and element replacements:

<xsl:template match="text()">

  <xsl:call-template name="str:replace">
    <xsl:with-param name="string" select="." />
    <xsl:with-param name="search">
      <t>!br;</t>       <!-- node names are unimportant -->
      <t>!emdash;</t>
    </xsl:with-param>
    <xsl:with-param name="replace">
      <br />		<!-- replacements by position for above -->
      <t>&#151;</t>
    </xsl:with-param>
  </xsl:call-template>

</xsl:template>

Thanks again, Dimitri and Jeni.
